KLM, Dutch airline founded on Oct. 7, 1919, and flying its first scheduled service, between Amsterdam and London, on May 17, 1920. Until its merger with Air France in 2004, it was the world's oldest continuously operating airline. Headquarters are at Amstelveen, Neth.

KLM Royal Dutch Airlines, founded in 1919 and known as the oldest airline in the world still operating under its original name, remains a major global carrier as part of the Air France-KLM Group. While it has faced significant challenges in recent years—including strict environmental regulations from the Dutch government seeking to limit flights at its Schiphol hub—the airline has not ceased operations. As of early 2026, KLM is focused on a massive fleet renewal program, replacing older aircraft with more fuel-efficient models like the Airbus A350 and A321neo to meet sustainability targets. However, travelers in early 2026 have seen some operational disruptions; in January 2026, KLM was forced to cancel hundreds of flights due to severe winter weather across Europe. The airline also continues to navigate the complexities of its merger with Air France, balancing its distinct Dutch identity and Schiphol-centric hub model with the broader strategic goals of the Franco-Dutch conglomerate.
